I have a rather esoteric case where I need to have some piece of code that will never execute but which still needs to be part of the compilation output. Although I could come up with my own, I'm asking the community: What is the simplest and fastest C# Expression that always evaluates to false and does not generate a compiler warning and preserves the enclosed block of code in the final build output?

Update: Since explaining the rationale behind the question was requested: The Mono touch linker performs static code analysis in order to strip all unreferenced symbols out of the final build to decrease the size of the generated binaries. This poses a problem with properties only accessed through reflection.
